[Octave-bug-tracker] [bug #58445] significant slow down in stable versio

Subject: [Octave-bug-tracker] [bug #58445] significant slow down in stable version for cellfun invocations which use function handles

Follow-up Comment #4, bug #58445 (project octave):

Matlab responds with


Error using cellfun
unknown option

Error in foo (line 11)
  cellfun ('numel', x)


The documentation says that cellfun only accepts handles to functions, not the
string name.  See https://www.mathworks.com/help/matlab/ref/cellfun.html.

Commenting out that code and re-running gives


ans = [13, 13]


So, it is picking up the handle to the subfunction.
